I have an older Craftsman jointer. I squared the fence to the table with the square on the infeed side.

 

With the square on the outfeed end, I can see a gap I could drive a truck through. Well, it’s actually not as bad as it looks. That is a precision machinist’s square in the picture and the fence is out of square 1/64”.

Do I…

1. Twist the fence to try and spring it to perfection (while crossing my fingers, hoping the cast iron doesn’t break).

2. Are you crazy? That is a woodworking tool and the twist is perfectly acceptable.

3. Other?

Is the fence twisted or are the two tables not parallel?

I think the tables are coplanar. I adjusted the infeed to the outfeed, inboard and outboard, with a Starrett precision straight edge.

You may have solved my problem. I have the infeed full down and it may twist on the stops. Let me check again.

Update…

I raised the infeed table to match the outfeed. That wasn’t the problem.

I vote to recheck the tables. Those are not co-planar. If you are just dead certain the tables are co-planar then the straight edge should not contact both ends of the fence. Then there is the unlikely chance that the fence is warped. Can happen but unlikely.

Have you thought of putting a shim where the gap shows instead of trying to bend it? I would put a playing card or something like that and not worry too much about it.

I think I agree that the tables are not coplanar.

I am going to try a different approach. Instead of adjusting so I think the straight edge is touching everywhere, I am going to lower the infeed table. Then I will measure the gap between the straight edge and the table, inboard fore and aft. Then outboard fore and aft. When all the gaps are the same, the table will be coplanar.

Infeed table is off a little, but it is almost bed time. I’ll fiddle with it a little tomorrow and post how I adjusted it.

I got a little side tracked and just got back to this today. I wrote an article on my blog about what I did…

Hi Steve, I had the same issue, fix was simple I mounted a 1/2 board to the fence and shimmed out the uneven portion until square. I gave up a 1/2” of the surface but it’s not that big and the only joint edging I have ever gone up to is 3” thick, acceptable for 4 1/2” jointer I think.
